Abstract
A developing device includes a developing case, a toner concentration sensor, and a positioner. The developing case stores a developer containing toner and carrier to develop a latent image on a surface of an image bearer. The developing case includes at least a part of a conveyance path of the developer. The toner concentration sensor detects a toner concentration of the developer in the developing case. The positioner engages with an engaging portion at a center of a sensor main section of the toner concentration sensor to determine a position of the sensor main section in the developing case.
